HARVESTER.

SPECIFICATION forming part of Letters Patent No. 323,954, dated August11, 1885.

(No model.)

To all whom it may concern:

Be it known that we, GEORGE XV. PAOKER, and CHARLES M. GRIM, citizens ofthe United States, residing, respectively, at Rock Falls andPierceville, in the counties of Whiteside and De Kalb and State ofIllinois, have invented certain new and useful 1mprovements inHarvesters; and we do hereby declare the following to be a full, clear,and

exact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters or figures ofreference marked thereon, which form a part of this specification.

Our invention has reference to harvesters; and it consists moreespecially of certain novel mechanism by which the machine can, at thewill of the operator, be automatically raised or lowered simultaneouslyupon its two carrying-wheels.

As the several parts of a harvester and their interrelation are wellknown, we do not 2 5 consider it necessary to show or describe more thanour improvements and their mode of attachment and operation.

In the drawings, Figure 1 is a plan of that portion of a harvesterembodying our inven- 0 tion. Fig. 2 is a longitudinal section in theline as 00 of Fig. 1, with a porton of the beam G broken away. Fig. 3 isa side elevation of the grain-Wheel and its adjacent parts, with thewheel B broken away. Fig. 4 is a 3 5 detached view of the location andattachment of the lever which actuates the clutch I.

A is the inner carrying-wheel, which revolves loosely on its axle A anddrives the machinery.

B is the grain-wheel.

D is a transverse shaft, on the inner end of which is rigidly attached aspur gear-wheel actuated by an internal gear on the inside of the rim ofthe wheel A. On the outer end of 5 the shaft 1) is rigidly affixed thebevel-gear D, which engages the bevel-gear E, fixed on the shaft E, thefront end of which shaft actuates the sickle, and on the rear of whichshaft is fixed the sprocket-wheel F, which latter, by means of thesprocket-chain F,

operates the roller F which carries the outer end of the revolvinggrain-platform. The chain F, midway, passes over and rotates thesprocket-wheel G, which rotates loosely on the shaft G, the latter beingsuitably journaled on the frame of the machine.

H is a bevel-gear on the inside of and in tegral with the sprocket-wheelG. The bevelgear H meshes with and rotates the bevelgear H, looselyjournaled on a stud, H suitably attached to the frame of the machine atright angles to the shaft G. The bevelgear II in turn engages androtates a third bevel-gear, H loosely placed on the shaft G, so that inthe onward motion of the machine the sprocket-wheel G and bevel gears H,H, and H continually revolve, while the shaft G is arranged to rotate atintervals, as hereinafter described.

I is a clutch feathered on the shaft G, between the bevel-gears H and Hand provided at each end with a ratcheted edge fitted to engage acorresponding ratcheted edge formed on the adjacent ends of the gears Hand H. The clutch I is so feathered on the shaft G 7 that it may bemoved longitudinally on such shaft. The interval between the gears H andH on the shaft G is such that when the clutch I is midway between suchgears it will engage neither, and the shaft G will remain 8o stationary,and it is obvious that when the clutch I is moved far enough to engagethe gear H the latter will rotate the shaft G in one direction, while ifsuch clutch is made to engage the gear H the latter will cause the shatG to rotate in the opposite direction.

K is a horizontal arm pivoted near its center to the frame of themachine, and fitted at its outer end to clasp and slide the clutch Iinto engagement with either the gear H or gear H The arm K is oscillatedat the will of the operator by means of a vertical lever, K, fulcrum edon the upper part of the frame of the machine, so as to be oscillatedforward or backward in the line of the progress of the 5 machine. Thelower end of the lever K is inserted in the inner end of the arm K, andby means of such lever the operator can throw the clutch I intoengagement with either of the bevel gears H or H or hold such clutch Ioomidway between such gears and out of engagement with either. Near itsfront end the shaft G is provided with a screw or worm, G which mesheswith a spur-gear, G lo cated beneath such worm G and loosely pivoted onthe stud G, attached to the outer face of the beam G forming part of theframe of the machine.

Integral with and inside the gear G3 is pro vided a sprocket-wheel, G",which actuates a sprocket-chain, ill, which latter in turn passes aroundand rotates a sprocketwheel, N, rigidly fixed on the axle A, which axlerevolves independently of the wheel A, intermittently, as hereinafterdescribed.

On the axle A is keyed a small spur-pinion, N, iitted to engage anupright rack, N rigidly fastened on the inner face of the beam G andfurnished with the inner gear-face, N. The rotation of the pinion N bymeans of the shaft G, ,worm G gear G, and sprocket wheel N, and axle Acauses such pinion N to traverse the gear-face N either upward ordownward, contingent upon the direction of the rotation of the shaft G.The axle A of the drivewheel A has a similar pinion, N, at its innerend, which engages a similar rack, N on the beam G". When the pinions Nare rotated so as to pass upward on the gearfaces N the machine islowered, and when the pinions N pass downward in such gearfaces N themachine is raised.

To prevent accidents resulting from too prolonged rotation of thepinions N, spaces are left in the bottoms of the racks N below thegear-faces N which, when the pinions N enter them, permit such pinionsto rotate without affecting the altitude of the machine; but thegear-faces N are so long that the pinions N would not be permitted toreach the lower ends of such gear-faces save through inadvertenee ornegligence in the operator.

At the upper end of the rack N Fig. 2, is located a trip, 0, ofbell-crank lever form, pivoted at its center to the side of such rackand having its inner or free end placed so as to be forced upward by thepinion l when the latter has advanced to near the upper end of thegear-face N. This action moves the outer end of the trip 0 backward, andsuch outer end of the trip 0 is connected,by means of the rod 0, to thearm K, between the fulcrum of the latter and the point of its engagementwith the clutch I, and when thus moved forces such clutch out ofengagement with the bevel-gear 11 and stops the furtherrevolution of theshaft G, and consequently stops the further revolution and verticalprogress of the pinions N.

The connection of the rod 0 with the lever O is formed by inserting theupper end of the rod 0 in the hole h in the outer end of the lever O,and placing on such rod a rigid collar, 0", so located that the lever 0will strike such collar when the clutch I is in engagement with thebevel-gear H but as the rod 0 can be freely moved farther to the rear bywithdraw ing partially from the hole h, it permits the clutch I to bethrown into gear with the bevelgear II in the manner before described.

It will be observed that it is the engagement of the clutch I with thebevel-gear ll which rotates the pinions N in the direction to cause themto climb the gear-faces N The shaft G at its rear end is fitted toreceive a crank, G by means of which such shaft can be rotated and themachine raised or lowered when stationary.

The foregoing description. has been con fined to the construction andoperation of the parts involved in raising and lowering the inner end ofthe machine.

We will now proceed to describe the mechanism employed in raising andlowering the outer or grain end of such machine.

P is a strong chain, the end link or ring of which encircles the axle Abetween the sprocket-wheel N and the pinion N, Fig. 2. The chain P ispassed upward and outward,over a pulley, b, suitablyjournaled on theplate 0, attached to theinner face of the beam G", and from thencepasses downward and outward under a pulley, d,journaled on the plate 0,attached to the outer face of the beam G the lower edge of the pulley (Ibeing slightly below the plane of the bottom of the platform oftheharvester. From thence the chain P passes transversely under the centerof such platform to the outer side of the machine, Fig. 3, under apulley,f, journaled in the lower end of. a yoke, S, fastened verticallyto the outer face of the beam T and forming part of the frame of themachine. The yoke S is provided with a vertical slot, S, in which isplaced, on suitable ways, 1, a plate, V, so that such plate V may movefreely up and down in such slot. ()11 the outer face of the plate V isformed integrally with such plate the horizontal stud V, which is theaxle or spindle of the wheel 1 The chain P, after passing as aforesaidunder the pulley f, passes upward behind the plate V and between thelatter and the beam T, and is attached to such plate near the upper endthereof, in a slot, a, in the upper end of such plate. It is obviousthat when the chain P is drawn upon by the pinions N passing down thegear-faces N such chain has the tendency to draw the plate V downwardtoward the pulley], and this upward pressure on the pulley f forces theyoke S and beam T upward, at the same time drawing the plate V and studV downward, which, as it moves the axle of the wheel B downwardrelatively to the frame of the machine, has the effect of thus raisingthe latter. When the pinions N pass up the gear-faces N and thus slackenthe chain P, the yoke S and outer frame of the machine attached theretosettle down ward correspondin gly, the pressure upward of the wheel Bforcing the plate V upward in the ways 9 in the yoke S. Thus the actionat the inner end of the machine in changing the elevation of the lat-IIO ter is communicated instantly to and accompanied with correspondingelevations and depressions at the outer end of the machine.

The change of elevation of the machine while the latter is in motion isa necessity caused by the varying height of the grain and occasionallodged or fallen areas. To make such changes automatically is quickerand involves less labor than by hand, and in addition it has been almostimpracticable to raise both ends of a harvester sinniltaneously by hand,and the raising one end alone would throw the machine out of shape.

The axle A has a fixed and unvarying altitude, regardless of the heightof the cut of the machine, and the advantage attained by collaring theend of the chain P on such axle is, that the machine is raised orlowered in precisely the same degree from its two fixed or carryingpoints, whatever may be the pitch or inclination of the parts in frontand rear of the line between such points. Such points are also intendedto be in the lateral line of the center of gravity of the machine, andthe draft of the chain P does not tend to oscillate the machine on itscarryingaxles, as would be the case were the points of attachment of thechain in front or in rear of such axles.

What we claimv as our invention, and desire to secure by Letters Patentof the United States, is

l. The combination of the bell-crank lever O, clutch I, rod 0, and thecollar 0 upon the rod 0, whereby such rod can be partially withdrawnfrom such lever, to permit the engagement of the clutch I with the gearH, substantially as shown, and for the purpose mentioned.

2. The combination of the rack N pinion N, lever 0, rod 0, and clutch I,such rod 0 being provided with a collar, 0 substantially as shown, andfor the purpose named.

3. The combination of the axle A, pulleys b and 4, chain P, yoke S,provided with the pulley f, the plate V, stud V, beam T, and wheel B,substantially as shown, and for the purpose specified.

4. In combination with the axle A, the chain P, loose collared at oneend on said axle and passing transversely under the grainplatform, andattached at its opposite end to a vertically-sliding plate, V, and meansfor operating the chain, whereby the inner and outer sides of themachine are simultaneouslyraised and lowered, substantially asdescribed.

5. The combination of the yoke S, rigidly attached to the outer side ofthe frame, the plate V, adapted to slide vertically in said yoke, andthe chain I, substantially as shown, and for the purpose specified.

In testimony whereof we affix our signatures in presence of twowitnesses.
